我的错误

您的SQL语法有错误;检查与MySQL服务器版本对应的手册，以便在第1行查看“post，view FROM nbb_groups WHERE group_id ='1''附近使用正确的语法

    $setting_query = mysql_query("SELECT * FROM nbb_settings");
    $setting = mysql_fetch_array($setting_query);
    if( isset( $id ) ) $group_id = userinfo($id,"group_id");
    else $group_id = "4";
    $groupinfo_query = mysql_query("SELECT acp,mod,post,view FROM nbb_groups WHERE             

    group_id = '$group_id'")or die (mysql_error());
    $groupinfo_row = mysql_fetch_array($groupinfo_query);

    $acpstatus = $groupinfo_row["acp"];
    $modstatus = $groupinfo_row["mod"];
    $poststatus = $groupinfo_row["post"];
    $viewstatus = $groupinfo_row["view"];

Answer 1

试试这个

$groupinfo_query = mysql_query("SELECT `acp`,`mod`,`post`,`view` FROM nbb_groups WHERE       
    group_id = '$group_id'")or die (mysql_error());

用`（反引号）

括起字段名称

字段名称MOD是MYSQL中的保留字...

Answer 2

mod是mysql关键字。

MOD(N,M), N % M, N MOD M;

更改字段的名称。

参考：http://www.w3resource.com/mysql/mathematical-functions/mysql-mod-function.php

Answer 3

示例Mysql查询：

<?php 
$t=mysql_connect("localhost", "root", "")//Coonector
or die(mysql_error()); 

mysql_select_db("category")//Set DB name
or die(mysql_error()); 

$result = mysql_query("SELECT * FROM `nbb_settings` ORDER BY `id` DESC")
or die(mysql_error());
while ($rec = mysql_fetch_array($result)){   
echo   $rec['name']."<br>";             
}
mysql_close($t);//Close Session
?>

请给我错误....

警告：mysql_fetch_array（）期望参数1是资源，第47行给出布尔值
